Vacuum Insulated Glass is ultra thin because it is constructed of two pieces of tempered glass with a narrow gap supported by metal pillars. It has higher resistance to deformation under external force, which doubles the wind pressure resistance and anti shock effect compared with common vacuum glass and tempered Low E argon insulating glass. vacuum glass has the obvious advantages Sound insulation performance Heat resistance Thermal insulation Sun proof function Anti condensation function Low e anti radiation function Long lifespan up to 50years Wind resistance Photochromic glass Fireproof and bulletproof performance Unique vacuum eye technology
